Starting on page 31 of the 2013 Service and Warranty guide is a list of components covered under the 7 year/70K mile CARB Warranty.

'EGR Valve (Low Pressure)' is one of the covered parts, along with the 'exhaust cooler for EGR', and many other high dollar parts like DPF, Turbo, fuel pumps, fuel injectors, etc, etc..

Caveat here may be the wording. If the vehicle fails emissions inspection. Well MD doesn't have an Emissions inspection. But it can be argued that it can't be inspected with a Check Engine light, so it would fail by default..

I dunno, service advisor hasn't gotten back to me (big surprise there)..

I need to finish researching and purchase a solution for reading codes, and diagnosing issues I guess (see post about Bimmergeeks product)..
